Grandma's revenge
When my three-year-old son opened the birthday gift from his grandmother, he discovered a water pistol. He squealed with delight and headed for the nearest sink. I was not so pleased.
I turned to Mom and said, "I'm surprised at you. Don't you remember how we used to drive you crazy with water guns?"
Mom smiled and then replied....."I remember."
